When Prince Charles walked beside his two sons, his father and his former brother-in-law behind Princess Diana’s cortege, savvy observers in London and around the world noticed something extraordinary. The future King, usually a pillar of protocol, had parted with tradition by wearing a blue Savile Row suit to the funeral. It was neither a symbol of disrespect nor a fickle fashion statement. Rather, says royal author Brian Hoey, "It was Diana’s favorite, blue suit, and she helped him choose it. She preferred him in blue rather than in black or gray. It was a lovely, silent compliment to her."
